PSYB65H3 : Lateralization LECTURE
Document Summary
The two hemispheres of the brain are not responsible for exactly the same functions. Bullet wounds to the brain; those that recovered had behavioral problems that differed. Wounds to the left hemisphere (in adults) result in : 100% of the patients will show some aphasic symptoms (i. e. problems with language). [ a-phasia; - implies -no-capacity for language -> mild, severe] these are either left handed or ambidextrous [ambidextrous clump with left handers; brain was wired to develop into left handers] the least amount of recovery was always in left handed individuals. suggesting that since 100% show left hemisphere damage aphasic symptoms: the left hemisphere is responsible for language function, handedness plays an important role. left hemisphere is critical for right handers. damage to right hemisphere showed few language problems; and rarely led to any kind of serious aphasia.
